<div dir="ltr"><div>Hi everyone,</div><div><br></div><div>I'm currently a PhD student at UCLA, and our current research interest is implementing and evaluating the routing idea from <a href="https://datatracker.ietf.org/doc/rfc9717/">RFC 9717</a> (A Routing Architecture for Satellite Networks) from the ns-3 <a href="https://github.com/markverick/ns3-ospf">OSPF routing module</a>, which is still in its early stage, and will be integrated with a simulated satellite mobility model, including handovers and terrestrial routing, like <a href="https://github.com/snkas/hypatia">Hypatia</a>.

<br>
Yes, attracting major players is important, and hopefully will happen organically over time. We are trying our best to include them, and might see some participation already in Bangkok.<br>
<br>
Both integration with terrestrial infrastructure as well as content delivery (which Ulrich also raised) are on our radar already. Thanks for bringing up; gives us a clear evidence of community interest!<br>
<br>
Best Wishes<br>

> This is not required for an RG but of course it is desired. I believe the attraction pull to involve major players can also happen slowly as RG starts discussing topics relevant to these players. We already see this in MAPRG which receives significant contributions from industry players. To accelerate this, it may be beneficial to define what the intended purpose/vision of this RG will be long-term (especially if it intends to stay as an RG).<br>

> On another note, I didn’t spot “interactions/integration of existing terrestrial Internet infrastructure with NTN” hinted in the RG description. This pretty much covers most interest from existing LEO ISPs and also questions such as “content delivery from space”. Is this an intentional oversight?<br>
